ABSTRACT:
A card holder for a rotary type information retrieving device such as a telephone number list, address list, and so on, in which a plurality of information-containing card cases are hangingly supported between a pair of mutually spaced rotary discs. In the present invention, a plurality of pins are projectively provided on the mutually opposed surfaces of the pair of rotary discs around their circumference and at an equal space interval provided among them, and a plurality of the information-containing card cases are hangingly supported between the rotary discs by the inwardly projected pins thereon. Each card case is formed by folding a single sheet of film material into a folder shape, and its bent portion, either in a single U-shape or in a circular shape in its cross-section, is made a pin insertion engagement part. The rotary disc has a concentric raised part at a position inside the train of the pins to prevent the card case from slipping out of the pin when it arrives at an upper position of the rotary disc in case the pin insertion engagement part is in a simple U-shaped cross-section, but has no such raised part when the bent portion is in a circular cross-section.
